API - SDK interoperability

This section helps developers who work with both the REST API and Mobile SDKs understand how they relate.

Endpoints in API vs SDKs	Mapping of every use case to its REST API endpoint and SDK method
Nutrition Data Model Mapping	How API response fields map to SDK model objects, nutrient calculations, and serving sizes
SDK V4	Upcoming SDK version aligned with the API data model

Key differences

• The SDK wraps the REST API — under the hood, every SDK method calls the same /napi/... endpoints documented in the API Overview.

• The SDK applies localization headers automatically if you've called updateLanguage, updateProductLocalization, or updateSearchConfiguration. In the REST API, you set these headers yourself. See Localization.

• For Android-specific details on how the SDK parses API JSON responses into model objects, see JSON Response Parsing in the Android SDK docs.
